is it necessary to use glass polish to kill water spots or can i use aio. any advantages???? im so far in the hole since i came here. im just trying to keep from buying something i don't need.
use glass polish. I've tried AIO on the windows and it doesn't work as well. Especially for waterspots. Just use vinegar on those. You don't need a paint cleaner. There are a few posts out there talking about what the results of using AIO on glass were. My experience was that it didn't work as well as glass polish.
Glass polish as AIO will clean and leave protection. The last protection about a week on the windshield and will start to streak. I have never used AIO on side windows. Glass polish also cleans the glass better than AIO.
